Those are cooked satoimo. I believe they are the members of potato family. The soup on the left looks like ozoni, so this pic is taken during the new year’s holiday in Japan.

Our cat fought with my dad for his plate of sashimi every time it was on the dinner table. But we tried not to give the kitty too much human foods. Our vet in Japan told us that what a human eats have way more salt than a cat can take. So for my dad and the cat, there was always a battle. lol.
